President Donald Trump dismissed Kellyanne Conway’s husband George Conway on Friday after he wrote a critical op-ed of the president in the New York Times.

Trump was asked by reporters about the op-ed as he left the White House to travel to Paris.

“You mean Mr. Kellyanne Conway?” Trump asked. “He’s just trying to get publicity for himself. Why don’t you do this, why don’t you ask Kellyanne that question, she might know him better than me.”

Conway wrote that Trump’s appointment of former Attorney General Jeff Sessions chief of staff Matt Whitaker as the acting attorney general was “unconstitutional” and “illegal” in the op-ed co-authored with lawyer Neal Katyal.
